Detailed Description
A serial port (UART) for communication with other serial devices.
Can be used for Full Duplex communication, or Simplex by specifying one pin as NC (Not Connected)
Example:
// Print "Hello World" to the PC #include "mbed.h" Serial pc(USBTX, USBRX); int main() { pc.printf("Hello World\n"); }
